Agent 'Nigel' manages SaaS + AV rental business on $640 Mac Mini
A solo founder running two businesses (SaaS + AV rental) deployed agent Nigel on a $640 Mac Mini M4 from Costco. Nigel does overnight autonomous work: give a directive before bed, wake up to deliverables.
What Nigel Does
- Overnight work: research reports, competitor analyses, lead lists while the founder sleeps
- API integration: figured out OAuth flows and connected 4 services in one session
- Bug fixing: found an SMS chatbot broken 10 months, diagnosed root cause, rewrote through 6 iterations
- Memory: daily markdown + long-term memory + semantic search via embeddings
